Nah..sump is inside the cabinet of the tank with ventilation tho. The way I have my pump in the tank it'd be a pain to move it outside since the bulkhead I drilled is at the top of the DIY w/d so that's out of the question of having it outside. Maybe I'll rig up a few PC fans...I know I should have about 8 of them lying around somewhere.
Well I do plan to get a chiller, since I'm planning on getting a 240g Long Tenecor tank so I figure to get a bigger chiller to cool off my 125 and 240 because I'm going to redo the setup.
In-wall for the tanks more than likely with a 55g DIY W/D...this way I'll mount the pumps on the outside.
But for now I'll try that...the 12V fans and see if that helps.
Thanks.
